The new iPad teardown

By , Mar 15, 2012

Every time Apple releases new hardware, the tech world awaits its inevitable teardown. Apple’s products are just as much a feat in engineering as they are sleek and beautiful. And everyone wants to know how they’ve done it.

The new iPad is no exception. Apple has managed to squeeze over 3 million pixels into the tablet’s Retina display, and add a high-speed LTE radio, all while maintaing [roughly]┬áthe same size, price and battery life of its predecessors.

So what’s going on under the hood to make it all possible? Let’s find out…

The folks over at iFixit get the award for the first total teardown of the new iPad. And while pulling apart Apple’s latest tablet, they’ve managed to uncover some interesting details regarding its components:

  • “The model numbers on the back of the 9.7-nch display lead us to believe this is a Samsung LCD.” This confirms earlier reports that Samsung was one of the only manufacturers trusted with making the Retina displays.
  • The A5X processor for iFixit’s particular iPad was made by Samsung in the first week of 2012. That kind of gives you an idea of the tablet’s production timeline.
  • The new iPad uses a Broadcom BCM4330 802.11 a/b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0+HS and FM Transceiver. This is interesting considering the reports we’ve heard that Apple would be going with Qualcomm’s new 4G chipset. Perhaps it just wasn’t ready in time.
  • The battery appears to makeup nearly half of the iPad’s innards. This makes sense considering it now has to support a high-resolution display and a battery-draining LTE radio. We also hear it takes forever to charge.

That’s about all for now. The iFixit team appears to still be going through the tablet’s final bits and pieces, so we’ll let you know if they find anything else worth mentioning.

    “We also hear it takes forever to charge.”
    I hate it when this happens with such expensive devices

      You know, this may blow your mind, but it just so happens those “expensive devices” use more energy than other devices. And that power consumtion means bigger batteries. You know how it takes longer to suck power out of bigger batteries? That same ratio applies to charging batteries as well. So bigger battery=longer charging time.

      I hope you’re writing all this down. It’ll help in the future.

        I know what you mean, but the battery isn’t THAT much bigger (according to the last post of iDB)… An extra 1 hour or 2 to charge is respectable. But any longer and I’m sure a lot of people will find it annoying.

        You’re just assuming that batteries won’t be more efficient in the future and therefore smaller… This trend of slapping in a bigger battery and calling it a day won’t last forever.

        It is not necessary to extend charging time of any battery if charging circuit and adaptor are built to accommodate, most battery can take a charge if 1C or more. In toy radio control batteries can be charged at eg. 10C and thus one can top up a 6000mA cell in say 20 minutes (heat and other factors come into play here)

      • As unreasoned it is to demand short recharge times for the increased output, I do want to note that capacitor based batteries are being developed. They should have a supposed recharge time of less then a minute.

        And by the way I’ve heard that the battery in the iPad HD last THE SAME as in the old iPad so if you use the same ratio then it should charge in the same amount of time !

    It uses Qualcomm MDM9600 – 3G and 4G wireless modem
